The carriage G is also as usual, consisting of ay bed-plate and transverse rolls, and, asusual, travels to and from the saws on the wheels c, which run on rails c', the whole beingreciprocated by means of the racks a, meshing with pinions b'xed to a horizontalzshaft, D, be-

hind the saw-bed A. Shaft D is `intwo sections, connected by a friction-clutch, so that ,the carriage C may be moved as wanted. These .are all as usual, and Ido not .alter thllla. f.. .5. i

To give effect to this motion of the carriage, I provideitwith a number .of .pivoted` headblocks or projections, d, attachedto the bed of theeV carriage, and rising abovethelevel ofthe rolls; thereof, and so located relatively toa rail in .transit that they project between it and the saws. Now, in moving the carriage away. from thesawsyin case the rail meets with any bstruction', it .slides back against' ,i the headblocks or projections, and is by them i supp0rtd- ,CMAN

As the head-blocksy or projections dare intended'to impinge upon the railat, Lor nearly at, its extreme ends, and as rails are made of various lengths, I provide for suchcontingency byplacing. two or more head-blocksorprojectionstoward each endof thecarriage, so that if. one pair be too far apart.. forvthe. rail it shall be met by the next pair, and so on.

As stated, the hot-bed lies directly abreast of' the rail-carriage, with its surface rails at right angles thereto. Swinging vertically on standards e, situated between the respective rails of the hot-bed, and in planes parallel with the rails, is a series of arms, E, which are, at pleasure, caused to rise or fall in unison by means of the camsi on the shaft Gr, which (as in my former application) is given motion by a crank, H, and piston-rod J, or other power.

The object of this rising and falling of' the all the arms into any desired curvature.

arms and their line of stops is to let them operate upon the rail and then sink out of the way, that no obstacle may exist to the dragging of the rail away over the-hot-bed.

These arms are shown in detail in Fig. 3, and are constructed as follows: Each arm consists of two portions-a xed pivoted part, m, and an adjustable part, n, secured thereto by means of tongues and grooves or other sliding mechanism. It is adjustable longitudinally on part m by the threaded lug o on its bottom, and a set-screw, p, passing loosely through the head of part m. By this means the combined length of the two parts-i. e., of the whole arm E--may be easily adjusted to form the ends of This may be done at any time, even during operations. ()n the arms, at the ends next the carriage C, I place loosely-swiveled stops q, which, in turn, are provided with the self-adjusting pivoted face-plates r, described in my former application. This furnishes a stop which is in all respects self-conforming to all inclinations and curvatures of rail-ange, so that there is no possibility of the rail being buckled or bent sharp.

Such capacity of variation is necessary to the proper effect, because the curvature to be given depends upon the amount of metal in the rail-head relatively to that of the flange or base, as such relation determines the degree of contraction in cooling suffered by the head and base; and as the head and base vary also in relative width, it is obvious that when laid on their side all rails will not lie so that their bases present the same angle to the plane on which they rest.

As it is designed that the operation of curvingtlie rail shall also effect its lateral straightening by the slight downward push exerted, the rolls must be kept accurately aligned, for which purpose their bearings must be occasionally looked to.

The rolls, being in accurate alignment, present a number of points in a plane which are practically equivalent to a continuous plate, and a downward pressure of the rail sidewise upon these will effect the lateral straightenin in a manner practically as eifectual as a ila plate.

The operation is as follows, all the movements being in the control of a single operator: After ascertaining the curvature required, the arms E are adjusted with their swiveled stops and face-plates corresponding tosuch curvature. The rail is then-delivered tothe carriage, and the latter propelled toward the saws, as usual. While the saws are acting the arms E are caused to rise` above the level of the rails and rolls. After the saws have done their work the carriage C is propelled back from them, and in so doing the rail upon it is Vforced against the face-plates by the head blocks or projections d, This effects at once the curving and straightening of the rail. Then the arms E are dropped and the rail dragged off to cool.

- Having thus fully described my invention, I claim and desire to secure by Letters Patent- 1. The combination of rail-carriage C, having head-blocks or projections as shown, with a curved line of stops, substantially as described, whereby, when the'` carriage recede's from the saws, it carries the rail against the stops, and thus imparts ytheprper curvature.

2. Thecombinationoftherail-ean'iageame, two or more head-blocks orprojections, d, the carriage-rolls, and a curved line of stops, substantially as described, whereby the retrogession of the carriage frein "the saws effects the desired treatment of tli rail. I

3. In combination witlilthe rail-carriage, provided with two or more fliead-blo'cks or projections, d, a curved line of stops capable of being adjusted toany desiredcurvature, substantially as set forth.

4. The combination o frtli carriage-frame and two or more head-blocks or projections projecting above the level? of the top of the carriage-rolls,- substantially as and for the purpose specie'd.

5. The combination of the-support e` swinging part m, movable part mthreade lug o, and screw p with a siiitalilelstol for the rail, snbstantiallyas set forth.

6. The combination of arm E, or part n thereof, with the swiveled bifurcated stop q, carrying the pivoted face-pieter; substantially as specified.- i

In testimony that Ielaiiiilthe foregoing I have 4hereunto' set my hand this 19th day of March, 1877.
